php Number conversion method: first determine whether the output amount is a number or a numerical string; then predefine an array for Chinese conversion and an array for unit conversion; then split the numerical string of the amount into an array ; Finally, replace the integer part with uppercase Chinese characters.
PHP digital amount conversion to uppercase amount
The code is as follows:
/** * 将数值金额转换为中文大写金额 * @param $amount float 金额(分) * @param $type int 补整类型,0:到角补整;1:到元补整 * @return mixed 中文大写金额 */ function convertAmountToCn($amount, $type = 1) { if ($amount == 0) { return "零元整"; } if (strlen($amount) > 12) { return "不支持万亿及更高金额"; } // 预定义中文转换的数组 $digital = array('零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'); // 预定义单位转换的数组 $position = array('仟', '佰', '拾', '亿', '仟', '佰', '拾', '万', '仟', '佰', '拾', '元'); // 将金额的数值字符串拆分成数组 $amountArr = explode('.', $amount); // 将整数位的数值字符串拆分成数组 $integerArr = str_split($amountArr[0], 1); // 将整数部分替换成大写汉字 $result = '人民币'; $integerArrLength = count($integerArr); $positionLength = count($position); for($i=0; $i<$integerArrLength; $i++){ $result = $result . $digital[$integerArr[$i]]. $position[$positionLength - $integerArrLength + $i]; } // 如果小数位也要转换 if($type == 1){ // 将小数位的数值字符串拆分成数组 $decimalArr = str_split($amountArr[1], 1); // 将小数部分替换成大写汉字 $result = $result . $digital[$decimalArr[0]] . '角' . $digital[$decimalArr[1]] . '分'; }else{ $result = $result . '整'; } return $result; }
After consideration, I found that the code I wrote before was not rigorous enough, so I have added a new version of the code
/** * 将数值金额转换为中文大写金额 * @param $amount float 金额(支持到分) * @param $type int 补整类型,0:到角补整;1:到元补整 * @return mixed 中文大写金额 */ function convertAmountToCn($amount, $type = 1) { // 判断输出的金额是否为数字或数字字符串 if(!is_numeric($amount)){ return "要转换的金额只能为数字!"; } // 金额为0,则直接输出"零元整" if($amount == 0) { return "人民币零元整"; } // 金额不能为负数 if($amount < 0) { return "要转换的金额不能为负数!"; } // 金额不能超过万亿,即12位 if(strlen($amount) > 12) { return "要转换的金额不能为万亿及更高金额!"; } // 预定义中文转换的数组 $digital = array('零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'); // 预定义单位转换的数组 $position = array('仟', '佰', '拾', '亿', '仟', '佰', '拾', '万', '仟', '佰', '拾', '元'); // 将金额的数值字符串拆分成数组 $amountArr = explode('.', $amount); // 将整数位的数值字符串拆分成数组 $integerArr = str_split($amountArr[0], 1); // 将整数部分替换成大写汉字 $result = '人民币'; $integerArrLength = count($integerArr); // 整数位数组的长度 $positionLength = count($position); // 单位数组的长度 for($i = 0; $i < $integerArrLength; $i++) { // 如果数值不为0,则正常转换 if($integerArr[$i] != 0){ $result = $result . $digital[$integerArr[$i]] . $position[$positionLength - $integerArrLength + $i]; }else{ // 如果数值为0, 且单位是亿,万,元这三个的时候,则直接显示单位 if(($positionLength - $integerArrLength + $i + 1)%4 == 0){ $result = $result . $position[$positionLength - $integerArrLength + $i]; } } } // 如果小数位也要转换 if($type == 0) { // 将小数位的数值字符串拆分成数组 $decimalArr = str_split($amountArr[1], 1); // 将角替换成大写汉字. 如果为0,则不替换 if($decimalArr[0] != 0){ $result = $result . $digital[$decimalArr[0]] . '角'; } // 将分替换成大写汉字. 如果为0,则不替换 if($decimalArr[1] != 0){ $result = $result . $digital[$decimalArr[1]] . '分'; } }else{ $result = $result . '整'; } return $result; }
